Add the potatoes and about one tablespoon of olive oil. Toss them around to coat them. Now go ahead and put the potatoes in the oven and give them a head start on the onions. I do this so that the onions won't be mushy by the time the potatoes are fully cooked. I roast them for about twenty minutes before adding the onions.

Once you've cooked the potatoes for a little while add the onions and the other tablespoon of olive oil. Return them to the oven and continue roasting for ten to fifteen minutes longer.

Lookin' good...

Place the cheese slices over the potatoes and pop them back into the oven until the cheese has melted.
